2009 FEB 24 - (VerticalNews.com) -- According to recent research from Serbia, "The microstructure and tribological properties of ferrous coatings applicable to cylinder bores were investigated in this study. Two kinds of ferrous powders were sprayed on Al-Si cast alloy (EN AlSi10Mg) substrate by atmospheric plasma spraying."

"Microstructural analysis showed that various Fe oxides were formed in the coatings. The presence of pores, unmelted particles, and Fe precipitates was also noticed. The pin-on-ring tribometer was used to carry out tribological tests under lubricated sliding conditions: sliding speed of 0.5 m/s, sliding distance of 5000 m, and normal...
